Question

Justify the statement, “Mitochondria are power houses of the cell”

Answer 1

Structure of mitochondria

Mitochondria is a double membrane-bound organelle in which the inner layer has folds called cristae helping in increasing the surface area. This membrane contains oxysomes, which take part in ATP synthesis, through the process of oxidative phosphorylation.


Mitochondria as power houses

Mitochondria are the primary sites of aerobic respiration. The synthesised ATP is not utilised by the cell instantly but stored in the mitochondria. When required, the ATP is hydrolysed releasing energy which can be used for various other metabolic activities. As the mitochondria are the sites of energy production and storage, they are called powerhouses of the cell.
